Substitutions on aromatic rings are generally carried out by electrophilic substitution, but for the synthesis of phenolic compounds and alkoxy benzene it is carried out by nucleophilic substitution, explain why this is so .
Ethane reacts with chlorine (Cl2) in the presence of ultra-violet (UV) light, to produce 1-chloropropane (CH3CH2Cl) and hydrogen bromide (HCl). As shown in the equation below.CH3CH3+ Cl2→ CH3CH2Cl+ HClDescribe the reaction mechanism of the reaction between ethane and chlorine to produce 1-chloroethane. The description should be detailed and must include the type of bond fission that takes place. You may sketch and insert suitable diagrams to aid your description if you wish.
Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov
regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called
an enol. The enol immediately rearranges to a more stable ketone via tautomerization.

- The Friedel-Crafts Alkylation of p-xylene n-propyl bromide can result in an isopropyl as well as n-propyl substitution. A) Write the chemical equation involved in this reaction. B) Which will be the major and minor product? What do you expect will be the ratio of n-propyl to isopropyl substitution for p-xylene?arrow_forwardTrue or False Considering that two carbon chains have equal number of carbons, but one has Fluorine and the other has Iodine, the one with iodine will have a higher boiling point. Mild oxidation of alkenes results to similar product as that of nucleophilic addition of water to aldehydes.arrow_forwardThe oxidation of an aldehyde is commonly carried out using potassium permanganate or potassium dichromate. In fact, the carbon alpha to a benzene ring is very reactive, hence it is possible to oxidize an alkyl benzene compound at the alpha position. Give the equation for the reaction of toluene to benzoic acid using potassium permanganate.arrow_forward

After shaking the residual gases with excess aqueous sodium hydroxide, the final volume was 30cm3.(All volumes were measured at room temperature and pressure.) The hydrocarbon has a number of isomers. Draw the displayed formulae and name 2 of the isomers of the hydrocarbon that illustrate each of the following types of isomerism below (i.e. 2 isomers must be drawn for each type of isomerism) (i) chain (ii)functional grouparrow_forwardUsing Friedel Crafts alkylation of benzene, a group of scientists discovered compound A, C3H3O, an optically inactive compound. They discovered that compound B, CsH;BrO, is produced during the halogenation process. When compound B is reacted with nitric acid, compound C, C3H,B1NO3, is formed. While Friedel Crafts alkylation of compound A produces compound D. This compound D was oxidised to produce compound E, C9H§O3 as a major product. Compound F, C10H1002, was produced by Friedel Crafts acylation of compound A. This compound F reacts positively with alkaline iodine and 2,4- dinitrophenylhydrazine. However, it returns negative results for Tollens' and Benedict's tests. Identify the possible structural formulae compounds A to F and explain your answers.arrow_forward
